Title: Directional aerial comprising metal discs
IPC: H01Q13/28
Filed: 1955-09-19
Abstract: 773,765. Aerials COMPAGNIE GENERALE DE TFLEGRAPHIE SANS FII. Sept. 19. 1955 [Sept. 18, 1954], No. 26755/55. Class 40(7) A directional aerial for the transmission or reception of wave energy comprises an imperforate metal plate 1 and at least one coplanar set of metallic discs 2 supported on metal rods 3 in a regular pattern. The aerial may be excited, or energy arriving from the correct direction received, by means of a receiving horn 6 at one'end of the aerial containing a primary element 4 attached to a feed cable 5. The plane or planes containing the set or sets of discs 2 are arranged parallel to the plate 1 and each disc is supported at its centre by a perpendicular rod 3. The centres form a regular system of quadrilaterals of a side length between 0.4# and #, # being the wavelength of the energy in air. Preferably the diameter of the discs is arranged to increase as the distance from the horn 6 increases so as to give a symmetrical energy density variation with respect to the centre line of the plate parallel to the end provided with the horn 6. The rods 3 are perpendicular to the electric field and do not participate in the radiation. As shown in Fig. 4 a V compound aerial system may be arranged having a radiation pattern L, and fed at the apex of the V by means of a waveguide 7 and two horns 9 and 10 oriented parallel to the plates 1, and 1<SP>1</SP>. A second set of surface elements may be mounted above the first on extensions of the support rods 3 and the exciting or receiving arrangement may consist of a waveguide along one edge of the imperforate plate pierced with appropriate radiating slots (Figs. 5 and 6, not shown). Four compound aerials such as that described with reference to Fig. 4 can be arranged on the four sides of a square support mast 8 to give a substantially omnidirectional wave propagation pattern in the horizontal plane and a narrow pattern in a vertical plane.

Patent GB-786166-A (GB)
Title: Improvements in electronic counters
Inventor: MCAUSLAN JAMES HAY LOUDON
IPC: H03K29/00
Filed: 1954-09-17
Abstract: 786,166. Electronic counting apparatus. IMPERIAL CHEMICAL INDUSTRIES, Ltd. Sept. 16, 1955 [Sept. 17, 1954], No. 26980/54. Class 106 (1). In a counting apparatus adapted for both positive and negative operation and comprising at least two multicathode counters, the carry (or borrow) between a lower counter and the next higher counter is effected by allowing a pulse through a first gate (or a second gate) to the next higher counter to cause addition (or subtraction) in that counter when any pulse to be added (or subtracted), or any pulse coincident therewith, overlaps in the first (or second) gate the trailing edge or a pulse derived from the trailing edge of the signal leaving the cathode preceding the zero cathode (or the zero cathode) of the lower counter. As described, the movements of a disc 10 coupled to the indicating shaft of a weighing machine, for example, are detected by photo-cells cooperating with radial markings on the disc whereby two overlapping trains of pulses are applied to a discriminating device 11 which provides corresponding signals on one only of its two output channels according to the direction or rotation of the disc 10, These signals are fed to " first " gates 12, 13, associated with the respective counting tubes C1, C2, &c. when the disc 10 is moving in the positive direction and to " second gates 14, 15, &c. when the disc is moving in the negative direction. A further supply of pulses is fed via a shaping circuit 16 to all the gates 12, 13, 14, 15, &c. and the ninth cathode K9 of each tube C1, C2, &c. is connected to the " first " gate 13, &c. of the next higher tube, while the zero cathode K0 of each tube C1, C2, &c. is connected to the " second " gate 15, &c. of the next higher tube. Thus, " carry " or " borrow " pulses are gated through to higher tubes simultaneously with the occurrence of the counting pulse giving rise to the " carry " or " borrow ". In a more detailed diagram (Fig. 3, not shown), multigrid valves are used as gates and mono-stable hard-valve trigger circuits develop pulses derived from cathodes K0 and K9. R.C. delay networks including blocking diodes serve to produce double pulses for the two guide electrode systems from each signal input pulse. Specifications 757,922, [Group XXXVII], and 771,052, [Group XXXVIII], are referred to.

Title: Improvements in or relating to cop feeding arrangements in looms
IPC: D03D45/20
Filed: 1954-09-17
Abstract: 758,796. Automatic cop-inserting mechanism for looms. HELD, H., WAGNER, C., HELD, M., SCHAAL, D., MUMMENHOFF, M., and GASSNER, A., [trading as EGELHAAF, C. C.]. Sept. 17, 1954 [Oct. 3, 1953], No. 27039/54. Class 142(2). The shuttle 37 has a diagonal opening 39 for-entry of coreless cops, the opening being restricted by an overhanging top portion 40 of the shuttle so that the cops have to be squeezed through it. The next cop to be transferred rests on a support plate 2 which is slidable by means of bosses 6 on a pair of rods 7 bridged by a hammer 4; the cop is retained by a flap 3 hinged at 8 to the plate 2 and held closed against the magazine 1 by links 9 anchored at 11. When the slay 36 operates the hammer 4 through a striker 35 and lever 34, 32, a latch 24 causes the support 2 to accompany the hammer in the first part of its downward movement; because of the links 9 the flap 3 turns about the hinge 8 until it becomes parallel with the plate 2, whereby the two parts constitute a shoot having an opening smaller than the diameter of the cop. At this stage, a cam 26 on the latch 24, encounters a surface 27, whereby the latch is lifted clear of the plate 2, which is held against further descent by a chain 29 becoming taut. Continued movement of the hammer squeezes the cop through the shoot 2, 3 and through the mouth 39 of the shuttle into the cop chamber. The shoot 2, 3 is kept in register with the mouth 39, as the slay moves about front centre, by a cam slot 31 engaged by a follower 22. The exit of the magazine is closed during the operation by a plate 14 carried by arms 15.

Abstract: 466,398. Casting-machines. WETHERILL ENGINEERING CO. Oct. 9, 1936, No. 27451. Convention date, Oct. 9, 1935. [Class 83 (i)] Moulds.-I n casting metal this is fed in superheated condition preferably under pressure, but the major portion of this superheat is withdrawn from the metal before it reaches the mould cavity. This may be effected by making an intermediate portion C of the gate 3 of flattened cross section. The cross section of the gate may be circular at each end A, B and preferably increases from the inlet A to the discharge end B. The gate may be formed in a separate member of grey cast iron, divided, to facilitate removal of solidified metal. A layer of solidified metal should form on the inside of the gate in use, but complete closure is prevented by the automatic increase in rate of flow at the restricted point until the mould is filled and shrinkage satisfied. For casting iron, or other metal of high melting point, under pressure, the gate 3 may be formed of refractory material of good heat conductivity and be included as part of a mould 4, which may be used with a casting- machine as described in Specification 459,304
